Enter an amount between $0 and $100,000. Use a decimal point.

How it is calculated

The professional fees amount is rounded to cents. Withholding is estimated by multiplying that base by 10% and rounding the result to cents. The remaining amount is the base less the withholding shown.

For example, a base of $123.45 gives withholding of $12.35 and a remaining amount of $111.10.

This calculation is an estimate. Whether withholding applies depends on the tax circumstances of the payment; confirm whether it applies to your case. This calculation alone does not determine an obligation to withhold.

Should I include IVA (VAT) in the amount?

No. Enter only professional fees before IVA (VAT). This tool does not add IVA or calculate an invoice total.

Can I use this to calculate income tax on my salary?

Salary income tax uses its own bracket table. For a gross salary, use the take-home pay calculator.
